Product details

Overview

VN920PEPTR-E from STMicroelectronics is a single-channel high-side driver IC designed for automotive and industrial load switching, featuring 15 mΩ R_DS(on), 30 A continuous output current, 36 V operating supply voltage, and integrated proportional current sense. It protects against shorted loads, loss of ground/V_CC, overvoltage (36 V shutdown), undervoltage (4 V threshold), and thermal overload - used in body control modules, lighting drivers, and solenoid control.

For engineers reviewing the VN920PEPTR-E datasheet, VN920PEPTR-E pinout, VN920PEPTR-E application, or VN920PEPTR-E equivalent, key selection criteria include its PowerSSO-24 package thermal performance (R_thj-case = 1.3 °C/W), CMOS-compatible input logic, analog current sense ratio (4400 typ. I_OUT/I_SENSE), and ISO 7637-2 transient immunity up to Pulse 5A (+86.5 V).

Technical Context

The device implements VIPower™ M0-3 BCD technology with active V_CC clamp, real-time current limitation, and automatic thermal shutdown with hysteresis (T_TSD = 150–200 °C, T_R = 135 °C). Its protection architecture includes dedicated detection circuits for under/overvoltage, overtemperature, short-to-ground, and short-to-V_CC, all feeding into a logic-controlled power stage.

Current sensing uses an internal proportional transconductance amplifier delivering I_SENSE = I_OUT/K (K = 4400 typ. at 10 A), with <±8% drift over −40 to +150 °C and 500 µs response delay. The output stage features fast switching (t_d(on/off) = 50 µs) and controlled dV/dt (0.5–0.9 V/ms) to suppress EMI during inductive load turn-off.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	15 mΩ max at I_OUT = 10 A, T_j = 25 °C - enables low conduction loss and minimal self-heating at full rated current
I_OUT Continuous	30 A - supports high-power resistive and inductive loads including headlamps and fuel pumps
V_CC Operating Range	5.5 V to 36 V - compatible with 12 V and 24 V automotive battery systems including cold-crank and load-dump conditions
Current Sense Ratio K	4400 typ. (I_OUT/I_SENSE) at 10 A - provides accurate real-time load monitoring with ≤±8% temperature drift
Thermal Shutdown Threshold	150 °C min. junction temperature - triggers automatic restart after cooldown to 135 °C, preventing permanent damage
ISO 7637-2 Pulse 5A Immunity	+86.5 V, 400 ms, 2 Ω source - withstands automotive load dump without external clamping diodes
Input Logic Compatibility	CMOS-level: V_IL ≤ 1.25 V, V_IH ≥ 3.25 V - interfaces directly with 3.3 V and 5 V microcontrollers without level shifters

Pinout & Package

Delivered in PowerSSO-24 package - thermally enhanced exposed-pad SO-24 variant with 1.3 °C/W junction-to-case thermal resistance when mounted on 8 cm² copper area. Pin layout optimized for high-current routing and thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning

INPUT	Digital control input	CMOS-compatible; includes 0.5 V hysteresis and ±1 mA clamp for robust MCU interfacing
OUTPUT	High-side switched output	Drives load between OUTPUT and GND; supports inductive demagnetization energy up to 462 mJ
CURRENT SENSE	Analog current monitor output	Delivers I_SENSE = I_OUT/K; open-drain capable with 400 Ω output impedance during overtemperature
UNDERVOLTAGE	Status flag output	Open-drain signal asserted low during V_CC < 4 V - enables system-level brown-out handling
OVERTEMPERATURE	Status flag output	Open-drain signal asserted low when T_j ≥ 150 °C - feeds diagnostic interrupt to host controller

Key Features

Feature	Design Value
Reverse battery protection	Integrated via GND protection network (resistor or diode-based); eliminates need for external series FET or diode
Proportional current sense	Factory-trimmed 4400 typ. I_OUT/I_SENSE ratio with <±8% drift - enables precise closed-loop load current regulation
Active V_CC clamp	Clamps transients to ≤55 V (at 20 mA) - meets ISO 7637-2 Pulse 1, 2a, 3a/b, and 5A without external TVS
Loss-of-ground detection	Monitors GND continuity in real time; forces OUTPUT OFF within microseconds if GND disconnects
Very low standby dissipation	≤10 µA supply current in off-state - critical for always-on automotive modules with strict quiescent current budgets

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN920SPTR-E	Same die, PowerSSO-36 package; R_thj-amb = 30 °C/W (vs 40 °C/W for PowerSSO-24); higher thermal margin at >25 A	Better suited for sustained 30 A operation in constrained airflow environments	Select when board layout allows larger footprint and thermal performance is prioritized over cost and size
TPS27081AQPWPRQ1	Lower I_OUT (8 A), no integrated current sense, 40 mΩ R_DS(on); AEC-Q100 qualified but lacks ISO 7637-2 Pulse 5A immunity	Limited to low-power lighting and sensor biasing; requires external current sensing and TVS for load dump	Choose only for cost-sensitive, low-current (<10 A), non-load-dump-exposed applications where diagnostics are not required

Compared with VN920PEPTR-E, STVN920SPTR-E offers superior thermal derating in high-ambient environments, while TPS27081AQPWPRQ1 trades integration and ruggedness for lower unit cost and smaller footprint - making VN920PEPTR-E the optimal choice for full-featured, high-reliability 30 A automotive switching.

FAQ

What is the maximum inductive load energy the VN920PEPTR-E can safely demagnetize?

The device supports up to 462 mJ of demagnetization energy at V_CC = 13.5 V, L = 0.3 mH, and I_L = 45 A - verified per Figure 20 in the datasheet. This rating assumes proper PCB copper area (≥8 cm²) and accounts for internal V_CC clamp behavior during turn-off. Exceeding this value risks overvoltage stress on the output stage.

How does the current sense output behave during thermal shutdown?

During thermal shutdown (T_j ≥ 150 °C), the CURRENT SENSE pin transitions to a high-impedance state with 400 Ω output impedance and delivers V_SENSEH = 5.5 V (typ.) - a diagnostic flag indicating overtemperature condition. This is distinct from normal operation, where I_SENSE remains proportional to I_OUT with ≤±8% drift.

Can VN920PEPTR-E drive loads with floating ground references?

No - the device requires a direct, low-impedance connection to system ground for loss-of-ground detection and proper current sense reference. Floating grounds disable protection functions and invalidate I_SENSE accuracy. If galvanic isolation is needed, use optocoupled input buffering with separate ground domains and ensure GND pin connects to the driver-side reference plane.

Is external reverse-battery protection required when using VN920PEPTR-E?

No external reverse-battery protection is required. The datasheet (page 17) specifies two validated GND protection networks - either a 1 kΩ resistor (Solution 1) or a small-signal diode (Solution 2) in the ground path - both leveraging the device's built-in loss-of-ground detection and internal clamp structures to survive −14 V battery reversal.
